I WHEEL;

Application filed May 211, 1923. Serial No. 640,400,

To all whom it may concern:

Be it known that I, IIIENRY" HOWELL, a citizen of the United States, "and a resident OfiMiO11TO6,d11 the parish of Ouachita and State .of Louisiana, have in vented certain new and useful Improvements in WVheels, of which the following is a specification.

This invention relates to an improvement in wheels of the type'embodying a demo unt able rim and forming the subjectmatter of my co-pending applications filed July 3, 1922, Serial No. 572,497 and filed March 28, 1923, Serial No. 628,372, and HIOIQPZIItlCU- larly relates to an improvement in the "looking arrangement for releasably securing the outer retaining flange-to the other elements of the rim and for securing the demountable rim as a. Whole on thefellyv or fiXe drim of the wheel. f L

The object of the invention is to provide a locking arrangement of this character which may be readily and easily. operated to assemble or disassemble the parts and wherein the liability of'the parts being bound by corrosions or being retarded intheirniovements by excessive friction is avoided.

An important object of the invention residesin the provision ofa locking'arrangement which is so constructed and organized as to'permit of dis'assembly even though the elements of the locking arrangement or the parts associated therewith should become distorted by reasonof severe or excessive shock or strain. 1 v a r I k p A further object is to provide a device of this character and having' -tl1e foregoing advantages and which is at the same time of simple and "durable ,constructioh',reliable in operation and easy and comparatively in- I expensive to manufacture and wherein the parts liable to become wornpor injured may be replaced or readilyrepaired, w v

c *Other objects and advantageso'f the in the construction, combination and arrangementof parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification, and in p hich:

The Wheel includes a felly 11 upon Which- 'thefelly band or fixed rim 12 is' shrunk or otherwise suitably secured,the felly band having a circumferential shoulder 18 constituting seat for the demountable rim and'having an integral lockingplate l lfat its outer circumferential edge whichllocking plate depends fromthe felly band and is disposed flush up againstthe outer lateral face of the felly 11. The felly 11 is slightly" reduced in width so that the thickness of the locking plate complements the width or thickness" of the fellyto provide tlie coinplete'felly of'standarcl dimensions; 1

QA'deniountable rim, designated generally 16, an inner tire retaining-flange 17 and an outer removableKtire retaining flange 18 (see Figures 1' and32). Thebase s ect1on 16 at15 isprovided and includes a base section vention reside in certain novel features of offthe demor'intablerim'is provided around its outer circumferential edge with, an into-i lgral depending locking plate 19' adapted to lie flush up against the locking plate 14 in assembly and!similarly the outer retaining fi'ange'18 includes an integral lockingiplate I 2O adapted tojlie flush up against thelockingt plate 19 in the assembly The lockingplate carries aplurality, preferably four, long studs designated generally at 21 and a plurality, preferably four, short studs, designated generally at 22.

These locking studs are of special design and construction and are organized with the locking plate 20 of the outer tire retaining flange 18 in the novel relation now to be described. As the construction, arrangement and relation of the long and short studs are identical, these studs difiering from each other only in length, a common description will serve for all. Each stud includes a shank 23 having at one end a head 24 pro vided with a pair of marginal ribs 25. The opposite end of the shank from that which carries the head 24 is threaded, as at 26, and

1 intermediate its ends the shank has rigidly formed thereona shoulder 27 which is polygonalin formation and preferably square.

' J The locking plate 20 with which the studs '21 and'22-:are associated is provided with a number of sockets, designated generally at 28, one'for each stud. Each socket 28 includes a seat 29 of polygonal formation and preferably square and in which the shoulder ing plateand on these threaded portions blind nuts or cap nuts 31 are threaded and coact with the locking plate to securely hold the-studs against vendwise movement. Of

course rotative movement of the studs is prevented by virtue of the engagement of the shoulder 27 with the walls of its seat 29.

The long studs 21 coactwith key hole slots 33 provided in the plate 14, the plate 19 be p ing provided with slots 34 permitting of the passage of the studs 21 into the slots 23.

The short studs 22 coact with key hole slots 35 provided in the locking'plate 19, the heads of the-studs 22 beingaccommodated in slots 36 provided forsuch purpose in the locking plate 14. By this arrangement the general 'and'broad features of which, as previously noted, are fully set. forth and form the subject-matter of my'co-pending applicationherein above referred to and to which reference is had for full illustration 0fthese features, the out'er tire retaining flange 18 maybe securely locked to the other elements of the demountable rim and the demountable rim as a whole may be locked wonthef' Wheel, this locking arrangement be-' ingentirelycomplete and secure as against Y the studs.

all Y except circumferential movement in one direction. For the purpose of preventing such circumferential movement any suitable means may be employed but preferably a locking arrangement of the type shown and described and claimed in my application filed March29, 1923, Serial No. 628,673 is utilized andembodies a wedge bar mounted in the felly and extended through. openings in the plates of the fixed rim and the demountable rim. 7 Certain of said-openings are designated at 37 in Figure 5.

s It is to be understood at this point that the locking plate 20 of the outer tire retain ing flange may be cut away in between'portions thereof in which the sockets 28 are formed or. may be made of uniform cross sec' tion throughout its extent as desired. Again it is to be noted that the projecting portions of the shanks of the studs and the cap nuts that encompass them afford convenient means for manipulating the'tire retaining flange through its movements, theseelements being adapted for coaction with a wrench or being adapted to serve as impact lugs.

It is to be noted that by virtue of the manner of constructing and mountin the locking studs on. the outer tire retalning flange that disassembly of the: parts. may be readily carried out even though the elements of the rim have been distorted by a severe shock or strain. Such disassembly may be carried out by rotating the cap nuts or blind nuts to disengage them from'the threadedportions 26 of the shanks 23 of the studswhereupon the removable tire retaining flange maybe taken from the wheel assembly leaving the studs engaged therewith and to be individually removed. Again any stud which has become worn or distorted may be readily replaced or repaired. Moreover a secure and reliable action is had for the studs arelield against turning by .the .coaction of the shoulders 27 with the seats 29 and they are held against endwise movement by the cap nuts '31, which may be also pinned or otherwise additionally secured to the shanks of. the studs if found desirable. Another advantage re sides in the construction of the head of These heads are formed with the ribs 25 which engage with the portions of the plates 14 and 19 with whichthese studs coact. This arrangement provides clearance 25 and serves a double purpose for preventing or reducing the tendency of corrosion and avoiding excessive fric-.

tional engagement between the heads and the parts with which they, coact. I' claim: I
